ABSTRACT:
An injection unit is disclosed with bridges for the plastification cylinder and for the plastification screw, which bridges are movable on fixed guide rods.There is a central injection cylinder and drive cylinders located diametrically with respect thereto. The pistons of the drive cylinders are firmly seated on the guide rods. A support device supports the injection unit on the machine pedestal of the plastic injection molding machine. The support device includes a fixed support, a movable support, and an elevation adjuster which transmits the supported load. The movable support is fastened to at least one of the bridges. With such an arrangement, bending of the support rods is virtually prevented during an injection operation.
